Public Working Drafts

A Public Working Draft is a working document that a Working Group has decided to distribute to the general public (for the purposes of obtaining feedback commentary) and which has been approved for such publication by the XBRL International Standards Board. When the Working Group believes that it is ready to advance a document to the next maturity level (Candidate Recommendation) it publishes a working draft and issues a "Last Call" for comments. If a Public Working Draft is in "Last Call" that status will be indicated here along with the closing date for comments to be received.


Table Linkbase 1.0 - December 21, 2011

Dimension Filters 1.1 - July 20, 2011

This Public Working Draft adds functionality to the current Dimension Filters (Formula) RECOMMENDATION.

The additional functionality has added DRS-aware axes of DRS-child and DRS-descendant. This is necessary in order that explicit dimension filters can support aggregation for SEC and IFRS filings. It is neither reasonable or possible for the author of formulas for such filings to be aware of extension taxonomy link roles, or to entirely avoid use of targetRole in comprising consecutive relationships (as is the case with the axes of the 1.0 specification). It is also not possible to emulate DRS-aware filters with the 1.0 specification dimension or concept-relations filters and current xfi functions.

The DRS axes require that the member have a <df:variable> specifying the variable that is bound to the parent or ancestor fact, because it is necessary for this filter to know both its primary item concept and dimension member. The DRS axes do not require link role. Arc role is not relevant for the DRS axes.

Feedback is invited and must be sent to rendering-feedback@xbrl.org.
